NbSiIr is a refractory metal intermetallic compound combining niobium, silicon, and iridium, designed for extreme-temperature structural applications. This material belongs to the family of advanced refractory alloys developed for aerospace and high-temperature industrial environments where conventional superalloys reach their performance limits. The addition of iridium enhances oxidation resistance and mechanical stability at elevated temperatures, making it a candidate for next-generation engine components and thermal protection systems.
